what is your way to remember these words?

Explanation:

• Prokaryotes: No nucleus, no membrane - bound organelles, have cell membrane, have circular DNA, have liquid cytoplasm, have ribosomes, may have cell walls, evolved early, simple, small, unicellular, in Monera kingdom.
• Eukaryotes: Have nucleus, have membrane - bound organelles, have cell membrane, have linear DNA in nucleus, have liquid cytoplasm, have ribosomes, may have cell walls (e.g., plants), evolved later than prokaryotes, complex, can be small to large, can be unicellular or multicellular, in Protista, Fungi, Plantae, Animalia kingdoms.
• Viruses: No nucleus, no membrane - bound organelles, no true cell membrane (have envelope in some), can have DNA or RNA, no liquid cytoplasm, no ribosomes, no cell walls, origin and evolution unclear, simple in structure but complex in function, smallest, acellular, not in the 5 - kingdom system. Memory aid could be creating acronyms or visual diagrams comparing features.
